The data contain concentration values of contaminants in air samples. The concentration were determined using two sampling mode: either passive or active followed by thermal desorption with gas chromatography and mass spectrometry.
The active sampling included up to 20 samples, and the passive sampling a total of 6.
Both sampling procedures and data is collected in different sites near to the petrochemical area
Active = active sampling mode
Passive = passive sampling mode
Concentration in ug/m3
0 concentration means non detected compound
